The Eurovision Song Contest seems to have been targeted by hackers who want to influence the vote for the final song selection in the qualifier.
Votes started flooding her yesterday application Melodifestivalen after Jon Henrik Fjällgren's performance, forcing the contest organizers to zero out the votes.
Mananger leader Christel Tholse Willers called the wave of votes "extreme overload".
"We are investigating the attack. "Our servers have been set up for a very heavy load, but what hit us was bumpy and extreme," Willers said.
From 3,7 millions viewers who watched her preliminaries Eurovision, about half a million of them used the application, increasing votes compared to last year by about 400%. Both voice (voice) and SMS are still the preferred 1,5 million viewer methods.
Safety testing by researchers claimed that Melodifestivalen was vulnerable to attacks.
The £100.000 app requires users to sign in via Facebook ή Google Plus, or register using their mobile numbers.
